Description

Pipeline powered turbine system generating potential energy from waste kinetic energy

technical field

The present invention relates to potential energy generated from useless waste kinetic energy, wherein the useless waste kinetic energy is excited, activated, stimulated, stimulated into potential energy from a dormant state.

Background technique

Sources of waste energy: Our urban "heat islands" are huge sources of waste energy. High-rise residential buildings (kitchens, household equipment, air conditioners, generators, etc.), business activities, industries, power plants, etc., there are high-temperature, hot radiator air (hot radiator air) and flue exhaust gas everywhere. The useless wasted kinetic energy is simply dissipated in the air. Additionally, tall buildings absorb/retain heat from the sun, business activity, and intensive transportation exhaust. The bigger the city, the bigger the heat island. Just imagine the enormous waste of kinetic energy emitted/dissipated into the air/wind from the tallest tower in the world: a 160-story, 828-meter (2,717-foot) man-made structure, the Burj Khalifa in Dubai.

Integrating, combining and merging the following scientific principles known in the prior art with the innovative system of the present invention (potential energy generation from waste kinetic energy at rest) can lead to entirely new functions and purposes, exponentially improving the system s efficiency.

1: "wind turbines farms"

(a) The basic principle involved in generating electricity from wind turbines is that a 20% increase in wind speed produces a 73% increase in electricity production, although air density decreases with increasing temperature and altitude. The cube of the wind speed is the main factor that generates electricity.

(b) A windmill cannot work at 100% efficiency because its structure blocks the flow of wind. Because a windmill works like an airfoil (the wing on an airplane), its structure also exerts backpressure on the turbine blades. The average efficiency of a wind turbine is around 20%.

(c) The basic principle of wind kinetic energy: the attainable "P" (power KW) is P=1/2pAV ³ , that is, 0.5×p(mass Kg/m ² )×A(fan area m ² )×V ³ ( (speed m/s) ³ )=KW.

2: "Hot Air Balloon"

Air pressure increases with temperature - hot air is less dense than cold air, so hot air is buoyant and rises, using vertical pressure to move up.

3: "Vertical Wind Tunnel"

"Indoor skydiving" enables humans to fly through the air through vertically generated wind forces. The basic principle of a wind tunnel is that a second pressure called static pressure is always present in the duct/duct/passage; it acts equally on each side of the duct - independent of velocity or direction of its movement.

4: "wind hopper"

Wind buckets are known to capture external wind for power generation as disclosed in Pakistan Patent No. 128764 owned by Mujeeb R. Alvi published on 30.11.1985 but wind buckets do not function in the manner of the present invention .

Contents of the invention

The present invention differs significantly from conventional windmills or cogeneration systems that generate renewable energy for a number of reasons.

a) The turbine towers of traditional wind turbine farms are very tall (80 meters or more) and very heavy (450 tons or more per tower), generating 3MW of energy, the present invention eliminates the need for large and very heavy The use of tall towers, and the elimination of their logical problems - are more difficult to produce, construct, transport and install.

b) The average efficiency of traditional wind turbine farms is very low - 20%, because its structure hinders the flow of wind and exerts back pressure on the turbine blades; while the present invention does not have these obstacles, and the efficiency is above 95%.

c) Traditional windmills rely on very irregular wind speed and direction (very variable factors) to generate electricity; while the present invention has the added advantage - static pressure (piping), which gives the system consistency in direction and speed, Can be managed, controlled and regulated.

d) In a cogeneration system, the flue heat is used to generate steam in the boiler for greater power generation, and the flue heat heats water for circulation, but thereafter, after part of the heat is dissipated, the exiting smoke The heat is simply dissipated into the environment as waste energy.

The present invention (Tube Power Turbine System to Generate Potential Energy from Wasted Kinetic Energy) has the following innovative features:

1. The "pipe power turbine" of the present invention is the only one in the world that stirs, activates, stimulates, and excites useless "waste kinetic energy" from a static state to generate potential energy without the use of oil or environmental pollution or greenhouse gases (carbon) Systems with increased emissions.

2. The potential energy generating "pipe power turbine" system of the present invention is located where the most useless waste kinetic energy is generated, but more energy is required.

3. The "Tube Power Turbine" of the present invention is the only system in the world that incorporates and combines all known scientific principles utilized individually by other different systems, these principles are as follows:

(a) "Wind Turbine Field": The cube of the wind speed which is the main factor in generating electricity.

(b) "Hot Air Balloon": Hot air is less dense than cold air, so hot air is buoyant and rises, using vertical pressure to move upward.

(c) "Vertical Wind Tunnel": A second pressure called static pressure is always present in the duct/duct/passage; it acts equally on each side of the duct - independent of velocity or direction of movement.

(d) "Wind bucket": capturing external wind for power generation, Pakistan Patent No.128764 published on November 30, 1985.

4. The 3 devices of the "pipe power turbine system" that generate potential energy from useless waste kinetic energy are: (I) the "channel power device" (internal device); (II) the "shielded funnel device" (external device ) and (III) "temperature control equipment" (external equipment). These 3 devices have a similar ejector device mechanism; while the two components (I) "channel power device" and (II) "shielded chimney device" have another similar defuser mechanism, the function of each device / operation is the same, as follows:

(i) The main mechanism of the ejector device is the same in all 3 devices. The ejector device body has an inlet, fits around the pipe body and is joined to the ejector device body; a slit is cut in the circumference of the pipe body at an oblique angle to form a slit venturi covering the interior of the ejector device body. venturi), the slit venturi tube is opened in the pipeline passage; useless waste kinetic energy is introduced under pressure through the main inlet of the ejector device, and is automatically discharged into the pipeline passage through the slit venturi tube at an oblique angle by rapid pressure . In the pipe channel, the waste kinetic energy of the waste creates a vortex above the slit venturi, creates a vacuum below the slit venturi, and draws more waste at low pressure through the opening of the pipe channel below it, as needed. waste kinetic energy or external air. The only difference is the flow direction (Figures 1, 3 and 5).

(ii) The defuser mechanism in both devices (excluding "temperature control devices"): erect the defuser plate vertically and hold it against the wall of the duct channel, the edges of the plate are at an angle, the face To the direction of flow, thereby finally transforming the vortex rotary motion into linear motion, increasing the velocity pressure inside the pipeline channel (Figs. 1 and 3).

(iii) Second device: The "shaded chimney" has an additional feature: it is provided with a vertical shaft connected to a large hemispherical device above the "shaded chimney inlet", The screened chimney inlet" is connected to the fan below. Wind from any direction spins the shaft and fan at high speeds, significantly increasing the movement and pressure of incoming wind drawn from all shaded chimney inlets (Figures 3 and 4).

5. Third equipment: "Temperature control equipment" consists of some shells/layers, in each layer cold air is introduced to transfer the mixture {hot air from radiator (75°C) and exhaust flue gas (484°C)} The high temperature factor is reduced to a reasonably safe level, thereby significantly increasing the volume and velocity pressure of the discharged mixture from the wasted kinetic energy (to be fed into the "pipe power turbine" system for potential energy generation) (Figs. 1 and 5).
